Two tree weta Hemideina ricta and H. femorata are predominantly allopatric on Banks Peninsula (South Island, New Zealand) except for four small areas of overlap. H. ricta was found over the outer eastern portion of Banks Peninsula including the eastern slopes of Akaroa Harbour whereas H. femorata was usually lower down on the eastern edge of Akaroa Harbour and west of this. H. ricta ranged from 20 m to 806 m in altitude whereas all H. femorata were found below 450 m. Ninety-four per cent of H.

Populations of ship rats (Rattus rattus), Norway rats (R. norvegicus), feral house mice (Mus musculus), stoats (Mustela erminea), weasels (M. nivalis), and ferrets (M. furo) were sampled with killtraps every three months from November 1982 to November 1987 in logged and unlogged native forest and in exotic plantations of various ages at Pureora Forest Park, central North Island. Mice (n=522 collected) were fewest in unlogged native forest, more abundant in road edge cutover forest, and most abundant in a young (5-10 year old) plantation.

Seven feral pigs (Sus scrofa), radio-tracked in relatively undisturbed rough pasture and forest near Murchison, New Zealand, for periods of 18-186 days, occupied home ranges of 28-209 ha. The immature pigs were significantly more active and had significantly larger home ranges than the adults, particularly adult females. The pigs were mainly nocturnal but they varied individually. The frequency of grazing and the rooting up of pasture and bracken (Pteridium esculentum) varied seasonally.
